Abstract

A datacast operator'"'"'s main page (36) is transmitted to receivers. The datacast operator'"'"'s main page (36) may include links to services and include information specific to the datacast operator and the network area it serves.

Claims

1. A method of datacasting, the method comprising providing electronic service guide (ESG) data relating to one or more services and providing supplementary data selectively provided by a datacast operator.

2. A method according to claim 1, comprising providing a main page including at least some of said supplementary data.

3. A method according to claim 2, comprising providing one or more data files including information for locating said main page.

4. A method according to claim 3, wherein said one or more data files include information for locating at least one service main page.

5. A computer program including instructions which when executed by a data processing apparatus causes said apparatus to perform the method according to any preceding claim.

6. A system for datacasting comprising providing electronic service guide (ESG) data relating to one or more services and providing supplementary data selectively provided by a datacast service operator.

7. Apparatus for datacasting comprising means for providing electronic service guide (ESG) data relating to one or more services and means for providing supplementary data selectively provided by a datacast service operator.

8. Apparatus for datacasting comprising a processor configured to provide electronic service guide (ESG) data relating to one or more services and to provide supplementary data selectively provided by a datacast service operator.

9. A method of operating a terminal for receiving datacast services, the method comprising receiving electronic service guide (ESG) data relating to one or more services and receiving supplementary data provided by a datacast operator.

10. A method according to claim 9, comprising receiving at least some of said supplementary data in preference to receiving said ESG data.

11. A method according to claim 9 or 10, comprising using said supplementary data to locate said ESG data.

12. A method according to any one of claims 9 to 11 comprising receiving a main page including at least some of said supplementary data.

13. A method according to claim 12, comprising providing one or more data files including information for locating said main page.

14. A method according to claim 13, wherein said one or more data files include information for locating at least one service main page.

15. A method according to any one of claims 9 to 14, further comprising receiving datacast data via a first network, receiving data from a second, different network and displaying at least some of said datacast data and at least some of said data.

16. A method according to any one of claims 9 to 15, comprising displaying a list of services and selecting one or more services.

17. A method according to any one of claims 9 to 16, comprising intermittently switching on a receiver to receive one or more time-sliced bursts of data and switching off said receiver.

18. A computer program including instructions which when executed by a data processing apparatus causes said apparatus to perform the method according to any one of claims 9 to 17.

19. A system for operating a terminal for receiving datacast services, the system comprising receiving electronic service guide (ESG) data relating to one or more services and receiving supplementary data provided by a datacast operator.

20. A terminal for receiving datacast services comprising means for receiving electronic service guide (ESG) data relating to one or more services and means for receiving supplementary data provided by a datacast operator.

21. A terminal according to claim 20 comprising means for receiving datacast transmissions and means for communicating with public land mobile network.
